Best challenging free puzzle game

This is the best free puzzle game I've found! The challenges start off simple and then get increasingly difficult. By the end, one puzzle took me over four hours to solve. I was frustrated enough that I would have taken a "hint" or "free pass" if offered, but none existed; so, I persevered. It was so rewarding to eventually figure it out!

Foundational Learning

This is great for building schema in young children or adding missing pieces to older students. The other review about the "worst game ever" missed the point. This does not use judgements of right and wrong, only feedback and results. I love it.


This is the worst game ever
